Email CSV Verifier

Upload a CSV with header email (optional first, last). You’ll download a CSV containing only verified rows.

CSV file

Tip: keep just one header row.

Perform SMTP handshake (slower; some hosts block it)

MAIL FROM used for the handshake is test@traderdan.pro (hard-coded on the server).

Depending upon the size of the file, this could take some considerable time. Please be patient. When your download finishes, you can merge the verified emails back into your original file.

Already verified and just want to re-attach names? Open the merge tool.
